'Arrow' ratings up for Huntress return

The return of The Huntress to The CW’s Arrow coincided with an uptick in the ratings Wednesday night for its “Birds of Prey” episode. Arrow was up 12 percent in the adults 18-49 demo and beat NBC’s Prince Harry special. But The CW’s newest drama, The 100, dipped 22 percent in the demo for its second episode. (Hang in there: I’m told the freshman sci-drama picks up considerably with some game-changing twists in the next couple weeks.)

Over on CBS, Survivor had the most-watched episode of its current Cagayan cycle Wednesday night and also beat Fox’s American Idol. Yet Survivor actually fell two tenths in the demo despite hitting a viewership high, which is a little odd. Idol was down a notch.

On ABC, new comedy Mixology jumped up 42 percent since it had an original Modern Family fueling its slot this week instead of a repeat. The Middle and Suburgatory were down slightly, as was Nashville. The rest of the grid was a lot of repeats. Full chart:
